Hi, folks. I picked up a sweet 97 Tahoe LS in September. So far, all is well and the truck is GREAT. However, my brake lights are not working. I checked the bulbs and the fuses...all ok. Parking lights work, turn signals work but no brake lights at all...even the upper LED. Cruise control cancel wasn't working either so I installed a new brake light switch. Cruise cancel is now working, but brake lights still a no-go. Any suggestions?
